Lighting a Studio Kitchen

I am shooting a series of short vignettes for a client next moth in a studio kitchen. They want it to look "warm and inviting" (warm up the WB) BUT look "clean." I was thinking a few big boxes at 45's and a big backlit silk overhead to fill the "food prep" area. Here's my question, any suggestions for 1. lighting the area under the cabinets and 2. any ideas for how to keep this inherently flat lighting setup interesting?
